"What kind of worlds do those humans have to abandon them?"
Before Emirose can say anything, Onichichi chimes in.
"The first batch of humans numbering a couple of millions, we had a hard time trying to relocate them is from a world similar to ours, a modern world but this one is invaded by beings from the ghost and spectral race, as you expected, none of the modern weapons were effective against such creatures."
Sean can already imagine it, ghost and spectral race are basically members of the undead race, they grow stronger by taking the lives of living beings.
"A couple of millions, tssh, what a massacre." He can't help but gasp.
A couple of millions might sound big but this is a world that is structured similar to theirs, if that's the case, their population should had been a couple of billions.
"Yeah, we are shocked to hear it too, they have been in constant battle for survival, for three hundred years, they were forced to survive in that world."
